A casino is a building or room in which gambling games are played. The term may also refer to an establishment providing entertainment, such as a stage show or DJ. Casinos are usually divided into three general categories: gaming machines, table games, and random number games. The gaming machines are usually operated by the players themselves, but table games and random number games are typically conducted by croupiers or dealers. Casinos are sometimes combined with hotels, restaurants, retail shops, and other entertainment facilities.

The MGM Grand on the Las Vegas strip is a legendary gambling den that attracts both hardened dollar spinners and curious newbies. This casino features the usual array of game tables and slot machines, but what really draws in the crowds is their state-of-the-art sports betting facilities. With 60 large plasma TVs, patrons can flick their chips on American football, boxing, martial arts, or soccer, while enjoying drinks and snacks.

Modern casinos use a variety of technologies to enhance security and monitor customer activities. For example, in table games, betting chips have built-in microcircuitry that interacts with the game system and allows casino employees to monitor amounts wagered minute by minute; and roulette wheels are electronically monitored to detect any suspicious or erratic deviations from their expected results. In addition, casinos employ a variety of security personnel, including physical guards and specialized surveillance departments. Some casinos also offer free spectacular entertainment or luxury living quarters to big bettors, as well as reduced-fare transportation and other inducements.
